Workaround for compilation error introduced in r54755

Scons used to fail because of couple of reasons:

- CMake does have WITH_DNA_GHASH enabled, Scons not
Which is a good question why?!
- This makes Cmake including BLI_utildefines in dna_genfile.c,
but scons missed this include
- This damn "bool" thing requires BLI_utildefines

And last question here is why would we want to use bool here =
It's just always ends up in headache without any visible benefit
of using it.

Well, at least now svn shall be compilable again..
